a. A random sample of 100 observations was drawn from a normal population. The sample variance was calculated to be s2 = 220. Test with α = .05 to determine whether we can infer that the population variance differs from 300.

b. Repeat Part a changing the sample size to 50.

c. What is the effect of decreasing the sample size?
